Inventor: VILLAX PETER
IPC: A61M15/00
Filed: 2006-05-16
Abstract: A dry powder inhaler for pulmonary or nasal use, comprising at least an inhaler body and a cartridge with one or more compartments each containing one dose of a drug. The compartment has holes to admit air and holes to deliver powder, which, in use, communicate with an inhalation channel in the inhaler body. To prevent the powder from leaking through the compartment holes before use, the air admission holes are of reduced dimension, thereby blocking or hindering powder exit under the force of gravity. When the cartridge is inserted inside the inhaler body, all its holes can be blocked. By sliding the cartridge in relation to the body until the inhalation position is reached, the holes come into in fluid communication with one another and with the inhalation channel, thereby allowing a flow of air to disperse and entrain the dose through the mouthpiece. Five embodiments are disclosed.

Filed: 1994-09-22
Abstract: FIELD: mechanical engineering. SUBSTANCE: adjusting device of the driving mechanism of a clutch engages the clutch so that the input speed of the gear to be measured corresponds to a reference speed signal that is preferably equal to 40-60% of the idle speed. This provides reliable coupling of the clutch at a negligible torque that corresponds to the braking torque. When the input speed is in the limits of the preliminary determined value of a reference speed signal, i.e. 4%, the device can determine the clutch contact point that corresponds to the extent of clutch coupling. This extent can represent the signal of clutch position or clutch pressure that is generated by a pickup used for automatic control of the clutch. If there is no measured signal of a clutch coupling, the clutch coupling extent can be a clutch coupling signal used for control of extent of clutch coupling. The contact point is determined as a difference between this extent of clutch coupling for negligible torque and shift of the clutch contact point. EFFECT: enhanced reliability. 19 cl, 7 dwg
